A few days ago, several countries signed ACTA, the Anti-Counterfeiting Trade Agreement. As you are probably aware, ACTA was drafted up in secret, and is basically Obama/Biden's attempt to impose the US' draconian pro-big business/big content protection laws on the rest of the world ('sign it, or else'). The European Parliament still has to vote on it, and as such, Douwe Korff, professor of international law at the London Metropolitan University, and Ian Brown senior research fellow at the University of Oxford, performed a 90-page study, with a harsh conclusion: ACTA violates fundamental human rights.

Innocent until proven guilty, is not really popular outside of common law countries. I bet Portugal, like most other Civil Law countries, have the Schroedinger's Cat of guilt/innocence doctrine. But depriving someone of possessions without a trial is however illegal.

Having studied my own county's constitution a lot, I can say that ACTA would violate the constitution without even touching on human rights issues. And the article that would be violated can't be changed without a 75% approval in a referendum.
